Isn't example below something like what you are trying to do:

====8<====
#include <stdio.h>
#include <stdlib.h>

int main(void) {
system("export PGDATABASE=\"test\"; export PGPASSWORD=\"test\"; export PGUSER=\"test\"; psql");

exit(0);
}
====8<====

? Here psql should connect to db 'test' as user 'test', password
'test'. Check if it works with pg_dump.

I hope that helps! BTW - there are also other ways to do that...
Check docs of your pg version. $PGPASSWORD is deprecated.
